Which of the following best describes the motion of a car traveling at a constant speed around a circular track?
The car moves with uniform circular motion because its speed is constant, but its direction changes continuously.
On a circular track the speedometer reading (speed) may stay constant, but the direction of motion changes continuously.
Since velocity depends on both speed and direction, the velocity is not constant even though speed is.
This is exactly the definition of uniform circular motion.
Hence, the answer is The car moves with uniform circular motion because its speed is constant but its direction changes.
